Hello, my 97th Mondeo tournament, starts to vibrate strongly when braking at high speeds up to approx. 100 km/h. Now I have looked at the brake discs. No edge on the discs feelable / coverings 50 % thick. But the brake discs have black dots / stains. Are original parts. Has anyone had this already? I think if the vehicle vibrates while braking down, I probably have to change discs and coverings anyway. But how this comes about, I’m interested. d has worn so little, can only Ford have built bad quality. Thanks to you. Tü Jokie
